"I often think you bring unhappiness on yourself, because if you don't like yourself very much, you allow yourself to be influenced by people who reinforce that"

In this quote, Lynn Johnston suggests that our own unfavorable self-perception can lead us to attract misery into our lives. She thinks that if we do not have a strong sense of self-respect, we are most likely to be influenced by others who also see us in a negative light. This can create a cycle of self-doubt and negativeness, as we continue to look for validation from those who enhance our unfavorable beliefs about ourselves. Johnston's words work as a pointer to take obligation for our own happiness and to surround ourselves with individuals who uplift and support us, rather than those who bring us down.
